Forget about everything else and just put everything on bitcoin. You are living with your parents, they pay everything for you, you got nothing to lose. If I was living with my parents, I would save everything and buy bitcoin monthly. If BTC doesn't keep rising you can still reach the 21 BTC holder group, then save this and retire in 10 years when the price makes you a millionaire.
Go all in on regret later. You are on a privileged position to profit from high risk high reward moves. No risk no win, and BTC is the best long term high risk bet.
It depends on what college degree you finish or what you really want to pursue in your life. People who does not even graduate or still studying can earn bitcoins and make money easily. You can start by investing in bitcoins and when you earn enough money then start your business, It was easier to sustain life if you are exposed in bitcoins.
